Definitions
- the present invention relates to a structure for removably holding a battery pack on an electronic apparatus and, more particularly, to a structure for holding a battery pack accommodating batteries which power a portable telephone or similar miniature electronic apparatus.
- the conventional structure relies on the elasticity of the lock lever in locking and unlocking the battery pack from the casing of the apparatus, as stated above.
- the problem with such a structure is that the lock lever breaks when bent beyond the limit of elasticity thereof, as determined by experiments.
- the wall portion prevents the lock lever from bending excessively against the excessive force tending to bend the lever outward.
- an electronic apparatus has a casing 1 to which a battery pack 2 is removably mounted.
- the casing 1 has a first engaging portion 3 and a second engaging portion 4.
- the battery pack 2 has a hook portion 5 and a lock lever 8.
- the hook portion 5 is engageable with the first engaging portion 3.
- the lock lever 8 is made of a plastic or similar elastic material and engageable with the second engaging portion 4.
- the lock lever 8 is bent in the direction A by finger until it has been released from the second engaging portion 4.
- the conventional structure described above has a problem that the lock lever 8 of the battery pack 2 is apt to break, as stated earlier.
- a battery pack holding structure embodying the present invention will be described.
- a battery pack 2a is removably mounted to a casing 1 included in an electronic apparatus.
- the casing 1 has a first engaging portion 3 and a second engaging portion 4 which are engageable with the battery pack 2a.
- the battery pack 2a has a casing 10 accommodating nickel-cadmium batteries thereon.
- the casing 10 has a hook portion 5 and a lock lever 6 which are respectively engageable with the first and second engaging portions 3 and 4 of the casing 1. Further, the casing 10 has a wall portion 7 extending substantially parallel to the lock lever 6.
- the hook portion 5 is brought into engagement with the first engaging portion 3. Subsequently, the battery pack 2a is pressed against the casing 1. As a result, the lock lever 6 of the battery pack 6 bends in a direction A and mates with the second engaging portion 4, thereby locking the battery pack 4a to the casing 1. To unlock the battery pack 2a from the casing 1, the lock lever 6 is bent in the direction A by finger so as to be released from the second engaging portion 4. In this condition, the battery pack 2a is ready to be removed from the casing 1.
- FIG. 3 is a rear view showing the battery pack holding structure in accordance with the present invention which is applied to a portable telephone by way of example. Dial keys and other conventional keys are arranged on the front of the telephone, although not shown in the figure.
- FIG. 4 shows the battery pack 2a removed from the casing of the electronic apparatus.
- the wall 7 outboard of the lock lever 6 prevents it from bending.
- the casing 10 of the battery pack 2a itself plays the role of a stop for preventing the lock lever 6 from bending. In this manner, the lock lever 6 is protected from damage even when subjected to unexpected external forces.
